The 4-km military-style run is an extremely popular format worldwide, and was brought to Ludhiana by Ireo, one of India's leading real estate developers, in association with sports management company, GameOn India. Sunday saw people across age groups, professions and gender take part in the event. "I had heard of such runs happening in the United States but to have it in Ludhiana was very exciting," said Dr Geeti Arora, one of the runners.

The first lot of 80 participants began the run in the early hours of Sunday. They covered a rugged 4-km course — full of wild grass and offshoots — that entailed crawling, jumping and climbing over nets, pits and tyres among other tasks. "Finding my way out of a pit full of freezing water was the highlight. The run was muddy and difficult but full of adventure and fun," said Gurvir Singh, who completed the course within an hour.
